LD侧面泵浦结构对增益分布特性的影响分析

摘要

通过光线追迹软件模拟及Matlab数据处理,从激光工作物质截面内吸收能量与所需面积关系方面对比分析了半环形结构激光二极管泵浦与类梯形结构激光二极管泵浦方式下增益分布特性的差异.通过理论计算及实际测量得出类梯形结构二极管泵浦情况下激光晶体内的增益分布更为均匀.%The characteristics of the pumping light distribution in working medium side-pumped by diode bars with different pumping structure is analyzed in this paper. With computer modeling and experimental test, the gain distribution characteristics in the working medium side-pumped by two different pumping structures is discussed by means of studying the proportion relationship between the absorbed pumping energy and the area needed. The comparison result illustrates that the homogeneity of the pumping light distribution in working medium is better in quasi-trapezoid diode structure.
